If the restaurant (and owner) are analogous to the government, could it not be inferred that the poorer of the patrons is given more while paying less? (not attempting to be classist, just seems like a reasonable inference)
I think its an ok analogy because its talking about federal government services and when talking about services like national security and currency protection they are all getting the same meal.
Oh, I dunno. Let's say I run a trucking company. I think I'm benefitting a lot more from the interstates (or state highways) than that guy who's broke who doesn't own a car.
Except that your trucks deliver food and widescreen TVs to the guy with the broken car for a cheap price.
They're getting a rather different legal system, mind you.
